⌂ Engravers one-by-one

The notation problem, creating a certain symbol, is handled by plugins. Each plugin is called an engraver. In this example, (some) engravers are switched on one by one, in the following order:

- note heads,

- staff symbol,

- clef,

- stem,

- beams, slurs, accents,

- accidentals, bar lines, time signature and key signature.

Engravers are grouped. For example, note heads, slurs, beams, etc., form a Voice context. Engravers for key signature, accidentals, bar line, etc., form a Staff context.
